ABSTRACT:
This lighting fixture enclosure comprises a back housing and an adjacent front housing separable from the back housing. The back housing includes a base; and the front housing includes a cavity in front of the base and a wall partially surrounding the cavity and terminating in a free end adjacent the base. The back housing includes a cradle on said base for receiving a peripheral portion of one end of a wire feed-through conduit. The front housing includes a notch in the free end of said wall for receiving another peripheral portion of the conduit. A projecting leg on said front-housing wall receives clamping means which, upon operation, forces the front housing toward the back-housing base, loading the leg in a bending mode, and also clamping the conduit end between said cradle and the wall portion bordering the notch.
